Dr. Pauline Demetrakopulos

Dr. Pauline Demetrakopulos, DDS

Dr. Demetrakopulos was born in Northern California and raised throughout the United States and Europe. She became interested in dentistry at the age of 15 while she was having orthodontic treatment in Germany. Soon after she began working as a dental assistant for a well-known restorative dentist in Nuremberg, Germany.

This sparked her enthusiasm for dentistry, and upon returning to the U.S., she enrolled at San Francisco State University and graduated with a BS in Cellular Biology. She went on to attend the University of the Pacific Dental School, where she graduated in 1984. Upon graduation from UOP, she completed a residency with Branemark Implant System. This is when she decided that she would focus on Implant and Restorative dentistry, as well as Cosmetic Dentistry.

Dr. Demetrakopulos opened her practice in downtown San Francisco, where she created some of the Bay Area’s most beautiful smiles. In 2004, she decided to move out of the big city, and start a practice in the heart of the Napa Valley Wine Country. She was now able to combine her love of dentistry along with her passion for food and wine. Her state-of-the-art practice in St. Helena is located in the restored depot building. Vineyard views and rolling hills are enjoyed outside the windows, and every day, the Napa Valley Wine Train stops outside the door.

Dr. Demetrakopulos works in partnership with her Artistic and Laboratory director, Mr. Jerry Parks. He is one of the best laboratory masters of porcelain fabrication in California. Working together, Dr. “D” and Mr. Parks custom make smiles, choosing the perfect shape and the shade to give patients the smile they have always dreamed of.

Dr. Demetrakopulos prides herself on her passion for dentistry, food, wine and especially people. She is creating beautiful smiles in the Napa Valley and would love the opportunity to meet you.
